Claims. (01. 173-340) This invention relates to a connector forconnecting up a local electric light circuit to a welders cable. Inconducting welding operais frequently located in situalt would be veryighting.

One of the objects of this vide a connector of to the welders cable, andwhich will supply current to a lamp which can be supported in a positionto throw light on the work.

A further object of a device of this kind, to the exterior of thespecial tools.

In practicing the invention, an insulated tapered spur or contact deviceis preferably emthe invention is to provide which can be readily appliedwelders cable without using of the return wire from the lamp circuit.

Further objects of the invention will appear hereinafter.

contribute to produce an efficient connector for temporary lamp circuit.

A preferred embodiment of the inventionis described in the followingspecification, while the broad scope of the invention is pointed out inthe appended claims. I I

In the drawing:

Fig. i is a perspective illustrating a welders welders cable by means ofa connector embodying this'invention. Fig. 1 indicates the work and asupport for the same, and certain parts broken away.

in the formof a long screw, the shank In practicing the invention Iprovide a connector I that preferably has a body, the axis or which isintended to extend substantially parallel with the welders cable 2 towhich it is to be attached. This body is provided with means forsecuring it to the exterior of the cable, which is a sheath 3 ofinsulation or insulating material. The body I is preferably constructedso that it can be readily applied to the cable by moving the samelaterally toward the cable, and at the same time manipulating the cableso as to engage it between two hooks 4 which extend out at the side ofthe connector. These hooks are spaced nector will attach itself to thecable. In this connection attention is called to Fig. 2, indicating thatat the ends of the bills 5 of the hooks, a throat such as the throat Gis formed, through which the cable must pass, and this throat is ofslightly smaller width than the diameter of the ca le.

In order to eflect the electrical contact with the conductor 9 withinthe welders cable, I prefer to provide a tapered conical spur in whichmay be in his hand and applies the electrode l9 to the placewhere theweld is to bemade :The electric light cord I4 is held in a cylindricalsocket or bore 20 that preferably extends into the body I from oneend inwhich an insulating bushing 2| may be provided. In the present instancethe return wire 22 passes across the bore 23 of the insulating block orbushing ll, Q

, and is carried through a notch or socket 24 near the forward end ofthe body I, from which point the bare wire 25 extends under a terminalor binding screw 26 which is threaded into the end of the body I togroundthis wire at the connectiOn. -1

It should be understood that the body I .is preferably constructed ofmetal so as to makeiit easy to ground the lamp circuit at the connectorif it is desired to ground the circuit at that point.

It is merely necessary, however, that when the connector is lying on itssupport, a ground will be established for the return wire 25. It is mostconvenient to have the body I made of metal because merely by lying upona grounded sup port such as the work, or a grounded table ll, a properground will be established.

In many cases where the welder is working on large work such as thewelding of tubing or boilers, or other large'industrial parts, the bodycan merely be permitted to lie on the work itself to establish theground. 30

Many other embodiments of the invention may be resorted to withoutdeparting from the spirit of the invention.

What I claim is:

1. A connector for establishing an electric light circuit fed by aninsulatingly sheathed welders cable, comprising an elongated body havingmeans for attaching the same to the exterior of the insulating sheath ofthe cable with the longitudinal axis of the body substantially parallelwith the axis of the cable, said body having an insulated spur ofconducting material to penetrate the insulating sheath to contact withthe conductor within the cable,'said spur having an insulated terminalfor attaching a wire for the electric light circuit; and a secondterminal grounded on the said body for connecting the other wire of thelight circui 2. A connector for establishing an electric light circuitfed by an insulatingly sheathed welders cable, comprising an elongatedbody having means formed with a gap on its side for enabling the body tobe attached to the exterior of the insulating sheath of the cable bymoving the body laterally toward the cable with the longitudinal axis ofthe body substantially parallel with the axis of the cable, said bodyhaving an insulated spur of conducting material to penetrate theinavamst co i,

sul ting she th 'to contact with the conductor wi the able, said spurhaving an insulated terminal for attaching a wire for the electric lightcircuit; and a second te al grounded on the body for connecting th otherwire of the light circuit.

3. A connector for establishing an electric light circuit "fed by aninsulatingly sheathed welders cable, comprising a body having spacedhooks projecting from the body enabling the body to be attached to theexterior of the insulating sheath of the cable by a lateral movement ofthe body toward the cable, said body having an insulated spur ofconducting material to penetrate the insulating sheath to contact withthe conductor within the cable, said spur having an insulated terminalfor attaching a wire for the electric light circuit; and a secondterminal grounded on the said body for connecting the other wire of thelight circuit.

4. A connector for establishing an electric light circuit fed by aninsulatingly sheathed welders cable, comprising a body having a pair ofspaced hooks, said hooks projecting from said body and extending inopposite directions at the side of the body, and each hook having a gapbeyond its bill capable of passing a cable, said hooks enabling the bodyto be attached to the exterior of the insulating sheath of the cable bya lateral movement of the body toward the cable, and bycompressing thecable, said body having an insulated spur of conducting material topenetrate the insulating sheath to contact with the conductor within thecable, said spur having an insulated terminal for attaching a wire forthe electric light circuit; and a second terminal grounded on the saidbody for connecting the other wire of the light circuit, said bodyhaving an insulating bushing carrying the insulating terminal, andhaving a bore through which the electric light wires may be passed insecuring the same to the body.

5. A connector for establishing an electric light circuit fed by aninsulatingly sheathed welders cable, comprising an elongated body havingmeans extending laterally therefrom to partially encircle, and attach,the same to the exterior of the insulating sheath of the cable with thelongitudinal axis of the body substantially parallel with the axis ofthe cable, said body having an insulated spur of conducting material topenetrate the insulating sheath to contact with the conductor within thecable, said spur having an insulated terminal for attaching a wire forthe electric light circuit, and means associated with the electric lightcircuit for grounding the same beyond the lamp.
